IC-CAP interview questions

I had 2 interviews (started before Christmas 2021) with them and received a tentative offer back in Feb 2022. They told me the next step would be submitting my resume to their prime contract. I waited a week and followed up. All I was told was "the position was closed and your information wasn't submitted". I would've appreciated if someone reached out to me first and let me know instead of letting me find out and was just told the position was closed. Overall, the interview process was lengthy and closure was unprofessional.
